' Thisinvention relates to certain improvements incasting means for linotype and the like associated with typographical composing machines, where matrices are released '5 from a magazine, or other device, by means of a keyboard or the like and assembled in lines of various lengths and sizes of char acters in the molds of said machines, where a melting-pot is arranged to deliver molten 10 metal into said molds up against the composed or assembled line of matrices to produce a type bar or slug in the usual manner. Modern stereotyping and printing methods and machinery, are placing heavy burdens "15 on the product of lrnotype and type casting machines, requiring lines, bars and slugs of greater strength and durability. The constant increasein size of type characters and the great possibilities for the future, denand that better means be provided for producing more desirabletypebars and slugs sufficiently strong and durable to properly support the printing surface of suchtype characters, bars, slugs and lines.

his the object of the present invention to provide a mold that will cast an improved linotype having one side wall of sufficient strength, with ribs or braces cast thereon to properly support the center, and an over- "hanging face or ledge whereby the face will have a greater width than the body topermit the introduction of a flat slug or bar similar to a spacing bar, beneath this overw hanging ledge to provide in reality another side wall,'whereby the printing surface along this edge will be suificiently reinforced to withstand repeated use without the usual sagging or caving in of the type face.

Particularly, the present invention relates to a novel form of mold, and also a novel form of typebar produced by said mold, whereby the type bar will be provided with the usual supporting ribs, and in addition, an overhanging {face orledge for the recep' tionof abar or slug to reinforce the printing :face along this edge of the type bar and to-give proper and suflicient support and strengtlrsat-thisusually weak point, and thus provided with a bar i'nay be positioned along prevent sunken and caved in characters of 1929.

such linotype bars or slugs upon repeateduse of said linotype. i

As hereinbefore stated, in the casting of the present form of linotype it is customary to provide a wall along one face of the bar and in combination with the wall or face a series of vertically disposed reinforcing ribs. These ribs are the full width of the face of the type bar so that the present molds for casting this linotype are provided with a head-piece whichin turn is constructed with a serrated or notched portion projecting into the mold cavity, said head-piece also being flange defining one side edge of the type bar, the other side edge of the type bar being defined by that portion of the main body portion of the mold forming the mold cavity. In these previously constructed molds the serrations or notched portions extend to the aforesaid flange so that the re inforcingribs in the type bar when cast likewise extend to the adjacent edge of the type bar and the full width of the face.

In applicants construction his improved mold is so formed, withparticulztr reference to thehead-piece,

ing ribs do not extend the full width of the face of the type bar whereby there is pro duced an overhanging flange along that side of the type bar opposite to the side provided with the continuous wall. lVith this construction of type bar a flat slug or spacing this edge of the type beneath the Voter-hanging flange of the type face 'n'oviding substantially a second solid wall for supporting this entire edge of the type bar. This improved linotype or type bar is produced by a very simple yet ingenious changein the construction of the present form of linotype'mold. This change or improvement is produced by simply foreshortening the serrations or grooves inthe mold head-piece orcap so that they do not extendthe full width of the mold cavity, as willbe explained more fully in thedetailed description to follow;

The present invention also contemplates that these spaced reinforcin some instances, where an unusually wide slug or type bar is desired, the idea of provlding the body portion ofthe mold, adjacent invention as applied to the mold cavity, with .a similar arrangement of longitudinal recess and serrations whereby the type bar cast in such a mold will be provided with a central longitudinal wall and oppositely disposed transverse reinforcing ribs, the opposite side edges of the type face overhanging, providing for the insertion un- Fig.5 shows a vertical sectional view of the improved type bar in'its assembled form with the spacing bar or slug inserted under the overhanging edge;

ig.10 is. across sectional View of this type bar illustrating the manner of setting --up the same in combination with the spacing bars or slugs inserted under the opposite overhanging edges of the typeface.

. Referringtothe drawings 1n. detail with particular reference to Fig. 1, 1 illustrates the body portion of the usual type of linotype mold and 2 representsthe cap portion properly spaced from the bodyportion by the conventional liners 3 and 4, all of which construction with the exception of certain details of the cap portion to be hereinafter more fully described, represents the well kn own construction of linotype mold.

.The cap portion 2in the pres .it instance of this improved mold is provided with a longitudinal rib 5 and inwardly projecting blocksor core sections 6 formed by spaced transverse grooves'7.

These grooves 7, it will be noted, do not extend'to the longitudinal rib5 but are foreshortened or terminated in' order to leave a space 8 between the end of the grooves and the longitudinal rib 5, whereby a longitudinal recess orthe like 9 will be produced. With this construction of mold, with'the particular improvement above referred. to, a linotype or slug "will be cast having the usual side wall 10 but with foreshortened transverse reinforcing'ribs 1-1 resulting in a type face --having a longitudinal overhanging flange or ledge 12 under which flange 12 is adapted tobe inserted or placed a spaclng bar or blocks or face of said cap and main 1,soo, es

slug 13in the setting up of the type bar whereby this overhanging edge will be properly supported and reinforced as clearly illustrated in Figs. l and 5 of the drawing.

Where it is desirable and necessary to cast a linotype or slug having an unusually wide type face, the construction or mold. asshown in Fig. 6 is, provided wherein,,similar to the cap portion, the main body portion of the mold is constructed with spaced blocks or core sections 1 produced by spaced foreshortened transverse grooves 15 in the same manner as previously described with respect to the cap portion. This construction will provide a longitudinal recess 16 along that part of the body portion defining one side of the mold cavity. With this construction a type of slug or type baras shownin Figs. 9 and 10 will be producedhaving acentral longitudinal wall 17 and oppositely disposed transverse foreshortenedrihs 18 wherein the opposite edges of the type face 19 will overhang or result in the overhanging flanges or the like 20. With. this construction two spacer bars or slugs 21 are used as clearly shown in Fig. 10 of the drawings. 7 Y

By means of this invention it will be obvious that not only many type bars or slugs can be cast with enlarged printing characters, with the greatest facility, but that the bars or slugs formed in this manner are of superior quality, strength and durabilityby reason of the'solid supportafforded'to the characters along both edges of the facethereof, and it will beobserved that the'form of mold as disclosed in the instant. application not only distinguishes from all prior types ofmolds, but the particular linotype cast in this mold is likewise distinctive.

The present invention has been shown merely in its preferred forms and by way of example, 'and as applied to aparticular type mold, but obviouslymany variations and alterationsmay be made, and the invention is not to be limited to any specific form or embodiment except insofar as such limitations are defined in the lVhat I claim is: g z 1 1.
